SPINNING-MACHINE SPINDLE.

SPEGIFICATILON forming part of Letters Patent No. 540,523, dated June 4,1895.

Application led March 3, 1894:. Serial No. 502,191. (No model.)

To all whom t may concern.'

Be it known that we, WILLIAM WIII'ILEY VINT and ARTHUR LIsTER HAGGAS,subjects of the Queen of Great Britain, residing at Oak- Worth, nearKeighley, in the county of York, England,have invented a new and usefulImprovement in Spinning-Machine Spindles, of which the followingdescription, together with the accompanying sheets of drawings, is aspecification.

Our invention relates to the class of spindles known as flier spindlesand has for its object the production of spindles that may be rotated ata high rate of speed without incurring excessive vibration while thepower necessary for effecting such rotary motion is considerablydiminished, this ob` ject being attained by the novel devices andformations hereinafter described and particularly pointed out in theclaim.

Figure l is an elevation illustrative of a spindle and made inaccordance with our invention. Fig. 2 is a view similar to and on thesame scale as Fig. 1, but shows certain parts of the bearings insection. Fig. 3 is a part sectional elevation illustrative of the lowerpart of our improved spindle and its bearings on an enlarged scale.Figs. 4 and 5 are drawings in detail on the same scale as Figs. l and 2and illustrate parts hereinafter referred to.

The spindle a, its iier b and the whirl or grooved driving pulley cwhich is securely ixed to the spindle a are of a well known type, andare arranged to revolve in connection with our improved parts asfollows: The lower end a of the spindle a. fits, so as to rotate freelywithin the loose revoluble sleeve or bush d, its pivotal extremity a2and its shoulder ata3 being the only parts of it that are in contactwith the bush d. This bush d has its extremity d formed to enter theopen- The bearing sleeve@ and bush d form the support and bearing forthe spindle aand on this spindleul beingyrotated, while at the same timethe bush CZ is left free to rotate with it, or `as nearly with it ascircumstances will allow, it follows that the friction upon said spindlea must -be divided between it and its bush d. Hence this said spindle dis not in this case retarded so `much as it is when it revolves instationary bearings.

-Into the lower end of the sleeve e we screw a bush p formed of softmetahthrough which the adjusting screw g passes by which means, on thenut?n being tightly screwed against this soft metalpall openings aresecurely closed and the possibility ofVv any leakage of the lubricantfrom" this part is entirely avoided.

To facilitate the lubricating of the spindle a within 'the bush d,openings s are made in this bush d to allow said lubricant to iiowfreely within, on'passing from the outer receptacle fm.

Having now described our said invention, what we claim is In aspindle-bearing for spinning-machines, the combinationof a supportingsleeve adapted to be xed to the machine-frame and having ascrew-threaded socket at the lower end, a soft-metal bushing screwinginto said socket and itself internally screw-threaded, anadjusting-screw entered through said bushing, a check-nut on said screwand designed to be tightened against the soft-metal bushing, 9 5

an anti-friction ball onthe upper end of `the screw, a loose bushjournaled in the fixed sleeve and resting on said ball, and the spindlejournaled in said loose sleeve.
